Public beach monitoring

Southeast Public Health monitors the water quality at municipally owned and operated public bathing beaches within our area. Monitoring occurs for 12 weeks, between early June and Labour Day and involves testing the water for bacteria as well as conducting a visual inspection of the beach.

Beach testing and monitoring is conducted in accordance with the Ontario Public Health Standards.

Southeast public beaches are sampled weekly. Some public beaches are sampled monthly due to their history of good water quality. If test results indicate poor water quality, the public beach is re-sampled and if necessary, posted as unsafe. The public beach will remain posted until test results confirm the water quality has improved and meets public health standards.

Signs warning against swimming are posted when beach conditions pose a potential health risk to bathers. Most often the posting of a beach is due to high levels of bacteria in the water.

Before entering the water look for posted warning signs and consider the following:

  • Has there been heavy rain in the last 24 to 48 hours? If yes, bacterial levels will be higher, and swimming is not recommended.
  • Is the water cloudy? If you can’t see your feet at adult’s waist depth, bacterial levels may be higher, and swimming is not recommended.
  • Are there any other problems with the beach? Large numbers of waterfowl, dead fish, algae or scum, dangerous debris, or public health warnings or postings indicate an increased health risk.

Beaches monitored by Southeast Public Health

The following beaches are monitored by Southeast Public Health. Results are updated daily from June to Labour Day.

What do the results mean?

The last water sample taken did not show harmful levels of bacteria. Due to the delay in receiving lab results weather and other factors can affect the water quality since the sample was initially taken. Refer to the list above of factors to look for and consider before entering the water.

A swimming advisory is in place and swimming is not recommended. High levels of E.coli bacteria were detected in the most recent water sample results. Swimming may increase your risk of developing minor skin, eye, ear, nose, or throat infections or stomach illness. If you choose to swim during a swimming advisory, avoid putting your head under water or swallowing the water.

The beach is closed. Beaches are closed when there is a significant risk to health and safety, such as a sewage or chemical spill. Beach closures are rare.

Occasionally results are not available for all beaches due to the sampling schedule in the region.
